Text and rubrics of the Roman Canon

The text and rubrics of the Roman Canon have undergone revisions over the centuries, while the canon itself has retained its essential form as arranged no later than the 7th century. However, there have been changes between the 1962 and 1970 versions outside of the preface and the Sanctus, specifically the 1902 English version of Nicholas Gihr's The Holy Sacrifice of the Mass (1902), and the version of the text from 1970.
